[yocto] [systemd-devel] How to automount

[Johannes Pointner]

I have to admit, I don't use systemd at the embedded system, but I use
the following files to do it for the usb flash drives:
/etc/auto.master:
+auto.master
/var/autofs /etc/auto.usb       --timeout=2

/etc/auto.usb:
usb1    -fstype=vfat,rw,sync,noatime,nodiratime,nodev,nosuid,noexec,uid=1000
   :/dev/usba
usb2    -fstype=vfat,rw,sync,noatime,nodiratime,nodev,nosuid,noexec,uid=1000
   :/dev/usbb

Furthermore I have a additional udev rule for the usb interfaces:
/etc/udev/rules.d/99-mount-usb-key.rules:
SUBSYSTEMS=="usb", SUBSYSTEM=="block", KERNELS=="1-1", ENV{USB_HUB}="usb2"
SUBSYSTEMS=="usb", SUBSYSTEM=="block", KERNELS=="2-1", ENV{USB_HUB}="usb1"

ENV{USB_HUB}=="usb1", SUBSYSTEM=="block", KERNEL=="sd[a-z]*", SYMLINK+="usba"
ENV{USB_HUB}=="usb2", SUBSYSTEM=="block", KERNEL=="sd[a-z]*", SYMLINK+="usbb"

But I also use automount on my desktop PC and there with systemd, but
no for a flash drives instead for cifs shares and this looks like
this:

/etc/autofs/aut.cifs-shares:
exchange -fstype=cifs,nosuid,rw,credentials=/home/h4nn35/.smbcredentials,dir_mode=0777,file_mode=0666
://server/exchange

/etc/autofs/auto.master:
+auto.master
/home/h4nn35/NetShares /etc/autofs/auto.cifs-shares --timeout=60 --ghost

I hope this helps.
